Abstract
A door for vehicles includes a mechanism that prevents unlatching of the door if the door handle is moved at a high rate of speed, but permits unlatching during normal (e.g. manual) handle operation. The mechanism includes a wheel having a wheel tooth. The door mechanism also includes an inertia lever having a first pair of teeth. An input lever has a second pair of teeth that engage the wheel tooth and the first pair of teeth. This engagement prevents rotation of the input lever only when the input lever rotates at a rate above a predefined maximum rate thereby rotating the inertia lever relative to the wheel. Rotation of the input lever unlatches a door latch.
